If there's a likelihood they can be accepted they will take it.
Besides all they have to do is focus on a board they are relatively good at.
I was referring to campaign managers who could simply deny to accept members who do merit abuse.
As far as the "board you are good at" is concerned, I don't think it's necessarily bad to have a specific board where you mostly frequent. I am mostly active in the bitcoin related topics, but I am casually looking most of the new threads to find topics that I may be interested in. If I don't write in other topics, is because I may not have any valuable knowledge to add. I think we share the same opinion here, but I am clarifying it to be sure.
You haven't looked at their posts. This is one person who writes something like "really" day and night, everywhere where it is necessary and not necessary.
I try to read the posts of many users, but this style, oddly enough, is unique and similar for these few accounts. Merits are not sold; they are transferred to their accounts, which, as it turns out, is not punishable, especially without strong evidence.
One word, "really," tears my eyes

out and causes an allergy; it appears so often in their posts because it is very difficult to read.
In addition, you see that all of them, one way or another, participate in signature companies.

No I haven't read their posts to be honest, but I guess I will because you caught my interest. Merits not being sold is, at least, a good thing. It would be a disaster if users had found a way to sell merits.
